Style analysis aside (and feel free to push it way, way, way to the side), it’s still surprising to find large, contiguous geographic blocs distinguished by glasses frames: bigger lenses dominate the edges of the country, while smaller ones dominate the center. What does that mean? Do we have to have a war, now? Which side will you be on?
